Abstract The structural characterization of sublayer surfaces of MIL‐101 is reported by low‐dose spherical aberration‐corrected high‐resolution transmission electron microscopy (HRTEM). The state‐of‐the‐art microscopy directly images atomic/molecular configurations in thin crystals from charge density projections, and…
Ti alloys are widely applied to jet engine components. Low cycle fatigue (LCF) strength of Ti alloys decreases with tensile stress dwell at room temperature (Cold Dwell Fatigue, CDF). CDF strength was influenced by stress level, microstructure, and dwell time. In order to study the effect of long time dwell for CDF pr…
The present review is based mainly on papers published between 2000 and 2020 and gives information about the properties of the Folic Acid and Beta Carotene in chemical and biological systems and its possible role in preventing several diseases. The main aim of this report is to highlight its role as an immunopathologi…
In high carbon steel, TTT nose temperature rises and upper baninte becomes easy to be formed with quantity of Si addition. Generation of upper bainite is reduced by boron addition. In this study, the influence of boron addition on isothermal transformation behavior in Si-added high carbon steel was clarified. By boron…
The main objective of this research is to investigate the rutting of modified mixtures with two additives of crumb rubber and polyethylene terephthalate (PET).Therefore, ITS method, resilient modulus and Dynamic creep were used to investigate asphalt behaviour with these two additives in this article. Modified blends…
In this article, a new method for complexity determination by using fractals in combination with an artificial intelligent approach is proposed and its application in laser hardening technology is detailed. In particular, nanoindentation tests were applied as a way to investigate the hardness properties of tool steel…
Current demand for new protective materials ensuring sterility is systematically growing. The purpose of this work was the synthesis of the biocidal N-halamine hydantoin-containing chitosan (CS-CMH-Cl) and characterization of its properties. The functionalization of the chitosan by 5-hydantoinacetic acid substitution…
In recent years, as semiconductor manufacturing processes have been steadily scaled down, the transistor count fabricated on a single silicon die can reach up to a billion units. Therefore, current multiprocessor system-on-chips (MPSoCs) can include up to hundreds or even thousands of cores and additional accelerators…
The precise control of the crystal morphology of metal-organic frameworks (MOFs) enables optimization of its adsorptive properties, as well as enables better integration within functional devices. However, the influence of such modifications on the dynamic properties of flexible MOFs is poorly understood. Here, we rep…
We observed the unusual crystal transformation from solid AgNO3 to Ag(I)‐encapsulated fullerene (C60) microcrystal by a coordination‐driven crystallization, when casting C60 solution on AgNO3 crystal. The strong binding of Ag+‐C60 ruptures electrostatic interactions within AgNO3 lattice, forming a binary hybrid materi…
The equation of state (EOS) of HfC and nanosized TiC at high pressure has been studied by means of synchrotron radiation X-ray diffraction (XRD) in a diamond anvil cell (DAC) at ambient temperature, and density functional theory (DFT) calculations. XRD analysis showed that the cubic structure of HfC and nanosized TiC…
Time-resolved X-ray tomography was performed to observe three-dimensional equiaxed-grain structure in Al-15mass%Cu alloy refined by inoculant TiB2 particles. The time resolution of as short as 0.5 s was achieved by using a pink X-ray beam at a beamline BL28B2 of SPring-8. A filtering method using a phase field model w…
With the emerging significance of creating an acicular ferrite microstructure to provide an optimum set of properties in steel, MnS precipitation behavior on a MnO–SiO2 inclusion at the solid-liquid coexistence temperature was experimentally investigated and thermodynamically elucidated in this study. Using a direct m…
Two different applications namely catalytic oxidation under solvent free conditions and optical power limiting studies were done on a mixed ligand ruthenium complex containing benzimidazole moiety and Triphenylphosphine. The complex was evaluated for its potential catalytic activity on the alcohol oxidation reaction i…
Abstract The DLPNO‐CCSD(T1)/CBS method combined with simple reactions containing small reference species leads to an improvement in the accuracy of theoretically evaluated enthalpies of formation of medium‐sized polyalicyclic hydrocarbons when compared with the widely used composite approach. The efficiency of the DLP…
Surface defects, which mediate nonradiative recombination, are detrimental to both the photovoltaic performance and stability of perovskite solar cells (PSCs). Improving photovoltage and fill factor (FF) in screen‐printed mesoporous PSCs is a major challenge for approaching the power conversion efficiency (PCE) of the…
Abstract Most of the insertion anode materials are approaching their specific capacity limitations. TiNb24O62, combining the merits of high theoretical capacity, large working potential and excellent safety, is a promising candidate for lithium‐ion batteries (LIBs). However, its poor intrinsic conductivity and relativ…
The article discusses issues related to the field of tractor construction, specifically to tracked and wheeled tractors equipped with various attachments that perform earthmoving, loading, transport and other works in industrial and road construction in special conditions that require additional cooling of the power c…
In ultrathin Cu(In,Ga)Se2 (CIGS) film solar cells, the CdS/CIGS interface may become one of the limiting factors for efficiency. The first step toward reducing the impact of this problem could be a surface treatment process to improve the quality of the front interface. The purpose of this study is to have a better un…
The correlation of several defects and optical and magnetic properties with Fe content in Zn1−xFexAl2O4(0.01 ≤x≤ 0.40) nanocrystals has been scrutinized through X-ray diffraction, OK-edge X-ray absorption near-edge structure, FT–IR, diffuse reflectance, photoluminescence and electron spin-resonance spectroscopies, and…
